- What is olive pomace?
- Olive pomace refers to the by-product of the olive oil extraction process, which is composed of residues of the pulp and fragments of the kernels. The residual oil is extracted from olive pomace through either cold or solvent extraction. This crude olive-pomace oil then undergoes refining to produce refined pomace oil. The olive pomace oil extraction process consists of the following 4 steps:
- How is olive pomace oil extracted?
- Today, olive-pomace oil can be obtained from the three olive oil extraction systems (Chap. 3): pressing, three-phase decanter, and two-phase decanter. Olive-pomace oil represents approximately 8 % of olive oil production.
- Why is oxidation of olive pomace oil difficult to remove?
- With respect to oxidation, as stated earlier, most of the alterations are produced during the drying step of the olive-pomace oil before extraction of the oil by solvent. Oxidized TAGMs and DAGs are difficult to remove during the refining process due to their polarity and volatility.
- What is winterization of olive pomace oil?
- It is an essential step in the refining of olive-pomace oil. Winterization involves a cooling of the oil at around 5–8 °C that allows the margarine (solid portion, mainly constituted by waxes and saturated triglycerides) to crystallize in 24–48 h. The process is followed by separation into two phases through filtration or centrifugation.
- Why does olive pomace oil have high triglycerides?
- Regulations (EC 2011) and IOC trade standards permit high levels of compounds related to the refining process. These modifications are mainly due to the drying process of olive-pomace oil, where the value of oxidized triglycerides can increase by up to 35 % (Gomes and Capornio 1997).
- What is Greek olive oil?
- Oil consisting of a blend of refined olive-pomace oil and virgin olive oils fit for consumption as they are. In 2001, the British Food Standards Agency removed from sale four Greek olive-pomace oil products that contained elevated levels of benzo (a)pyrene.
